Reducing DSP schedule bottlenecks in a wireless communication system

Abstract

In one embodiment, a method is provided of communicating in a wireless communication system. The method comprises (a) setting a decrement burst variable to be equal to a predetermined number representing a number of bursts of data from which to prematurely decode a USF codeword, (b) receiving a received burst of data comprising USF related data related to a portion of a USF codeword, (c) extracting said USF related data from said equalized received burst of data, (d) determining if a burst number variable is equal to said decrement burst variable, (e) incrementing said burst number variable and repeating (b) through (d) if said burst number variable is not equal to said decrement burst variable, and (f) decoding said USF codeword if said burst number variable is equal to said decrement burst variable.

     8. The method of  claim 1 , wherein said communicating is performed using a GSM/EDGE standard. 
   
   
     9. A mobile station for communicating over an RF channel, said mobile station comprising:
 a first module for receiving a burst of data comprising codeword related data corresponding to a portion of a codeword; 
 a second module for extracting said codeword related data from said burst of data; 
 a third module for incrementing a burst number variable and repeating said receiving and extracting steps if said burst number variable is not equal to a predetermined number; and 
 a fourth module for decoding said codeword if said burst number variable is equal to said predetermined number. 
 
   
   
     10. The mobile station of  claim 9 , wherein said predetermined number represents a number of bursts of data from which to prematurely decode said codeword.

     12. The mobile station of  claim 9  further comprising a sixth module for determining, before the third module increments said burst number variable, if a data quality of said burst of data is higher than a threshold, and if so enabling said fourth module to decode said codeword, and if else enabling said third module to increment said burst number variable. 
   
   
     13. The mobile station of  claim 9 , wherein said codeword is an uplink status flag codeword. 
   
   
     14. The mobile station of  claim 9 , wherein said communicating is performed using a GSM/EDGE standard. 
   
   
     15. A computer program product including a computer-readable medium having stored thereon a computer software program executable by a processor in a mobile station of a wireless communication system, said computer software program comprising:
 code for causing the mobile station to receive a burst of data comprising codeword related data corresponding to a portion of codeword; 
 code for causing the mobile station to extract said codeword related data from said burst of data; 
 code for causing the mobile station to increment a burst number variable and repeating causing the mobile station to receive a burst of data and extract codeword related data if said burst number variable is not equal to a predetermined number; and 
 code for causing the mobile station to decode said codeword if said burst number variable is equal to said predetermined number.
